CAN OPENER.

Application filed December 15 1924. Serial No. 756,010.

This invention relates to hand operated can openers princlpallyfor round cans and has for its object the provision of means whereby the can need not be held during bear on the operation, and resultingin much greater speed than with other openers of this type, yet withal a simple, durable construction adapted to sell for a small price.

My improved can opener is shown in the drawings accompanying this application, and in Figure 1 is shown in plan in position on a large can ready to start the cut, and in Figure 2 the inner ends of the levers only are shown with knives contracted to cut a much smaller can.

Figure 3 is an elevation of the fixed blade on the ends of the levers as seen in direction of the arrowv3, and Figure 4 is a side elevation of the adjustable blade of each lever as seen from the line IVIV of Figure 1.'

Figure 5 is a sectional justable lever joint.

Briefly described my can opener comprises a pair of levers 1 and 1 adjustably pivoted together in slots 2, 2 and each carrying fixed blades 3, 3 at one end and formed intp suitable handle grips 4, 4 at the other en Each lever also carries a slidable blade 5, 5 which may he slid along the levers so that all four blades may be pushed through the end of the can when placed in the position shown in Figure 1 and after which the handle ends 4;, 4" are simply pulled toward one another until the four blades projecting through the can each make a quarter revolution until they stop by abutting elevation of the ad off.

As the handles come together in finishing the out they are preferably ofi'set as shown so that the grip does not have to be changed while operating the device.-

The blades are pointed as shown in Fig I,

out until the cut is finished, as shownin' one another and. therend of the, can is cut Figure 4- The sliding blades 5, 5" ,are formed to slidably embrace the levers as shown and the metal of the sliding oortion is also struck up toform a small lug to in sure the cutter blade remaining adjacent the can edge in cutting and not crawling inward as with some cutters; Also the blades are preferably slightly crowned on their outer surfaces and sharpened outwardly from the inner side as indicated at '8 in Figure 1 so that the blades will normally be carried outward against the side of the can. I I v a To facilitate adjusting the levers in their slotted engagement to different sizes of cans,

I preferably provide teeth 9 along one edge only of each slot and a rivet pin in the form of a small pinion 10'engaging the teeth and having a plate 11 riveted at each end to hold the assembled levers together, thus, when the levers are pushed in or out to ad just them the pivotal point is always the proper distance from the end blades 3, and 3f to fall over the center of the can when the sliding blades 5, 5' are adjusted to the proper position for the particular can.

By thus providing a pair of levers pulled together by the force of both arms and re taining the bladesin place by means of the lugs 6 and 'i' it is not necessary to hold the canv at all and the can top may be cut out in the quickestspace of time with the'very minimum of labor.

I-claim:

1. A can opener comprising a pair of levers pivoted to one another, two blades on each lever adapted all to penetrate the end of a can and to cut around the edge of the end upon pivotally operating the levers.

2. A can opener comprising a pair of levers pivoted to one another, two blades on each lever adapted all to penetrate the end of a can and to cutaround the edge of the end upon pivotally operating the levers, said levers having sliding adjustment on the pivot. i I

3., A can opener comprising a pair of 1cvers pivoted to one another, two blades on each lever adapted all to penetrate the end i of a can and to cut around the edge of the end upon pivotallyoperating the levers, said levers having sliding adjustment on. the, pivot, and the pivotv being in the form of a pinion and engaging teeth on opposite sides respectively of a slot formed in each lever whereby the levers are geared together in their adjustment.

4. A can opener comprising a pair of le- 5 vers pivoted to one another, two blades on each lever adapted all to penetrate the end of a can and to cut around the edge of the end upon pivotally operating the lovers, said levers having offset handles adapting the levers to be revolved on their pivotal 10 connection to bring the blades of opposite levers substantially in abutting relation.
